my observation, though it may occur occasionally in 

 localities outside of its usual range.'] The same 

 remarks apply to var. lilacina, which is included. It 

 should be noted that the var. pallida is very pale 

 purplish, not pale yellowish, as I .have seen it 

 described. 



12. IT. hortensis, var. roscolabiata. I have pre- 

 ferred for this the prior name hybrida, Jeffreys, but 

 owing to the confusion that has existed about so- 

 called hybrida, there is something to be said in favour 

 of Mr. Taylor's name. It would seem, however, 

 that this form was included in Colbeau's var. sauveuri 

 (1866), although Westerlund gives that as a synonym 

 of 'var. fuscolabiata, Kregl. 



13. H. hortensis, var. umbilicata, whichlis'omitted, 

 is practically the same as Westerhmd's var. perforata 

 (1871). The var. major is also left out, and rightly, 

 since it has never been defined ; but I have taken a 

 remarkably large form, which it seemed possible to 

 include under Westeilund's var. crassa. 



14. H. hortensis, var. sinistrorsa. Credited to Mr. 

 Taylor, but did not Miss F. M. Hele first name it in 

 "Journ. Conch.," vol. i. p. 248? The same remark 

 applies to the sinistral form of H. aspersa. 



15. H. arbustorum. What has become of var. 

 Baylei ? Is it considered the same as var. alpestris, 

 following Servain ? The var. alpestris, according to 

 both "Westerlund and Servain, should be known as 

 alpicola — the last-mentioned author regarding it as a 

 species. 



16. H. cantiana. Why are not the small varieties 

 included ? The var. albocincta must] be very similar 

 to var. ancona:, Issel, judging from the description of 

 the latter. 



17. H. cantiana, var. albida, Taylor, is a synonym 

 of var. alba, Colbeau, 1866. 



18. H. rufescens, var. depressa. Locard named a 

 vav. depressa, but I believe did not describe it. I 

 have not seen any description by Mr. Taylor either, 

 but it may well be in some publication to which I 

 have not access in Jamaica. 



19. H. hispida, var. albida. By the union of con- 

 cimia with hispida, there have come to be two vars. 

 albida. The H. concin?ia, var. albida of Jeffreys 

 may stand as H. hispida, var. alba, having been 

 called concinna, var. alba, by Mr. Williams in 1889. 

 ("Land and F.-W. Shells," p. S3.) 



20. H. caperata, var. nana, is a distinct little form, 

 which might well have been included. I found it 

 forming a local race at Teddington, and have given 

 specimens to the Conchological Society. 



21. //. virgata, var. subdeleta, is a characteristic 

 Biitish|form, though occurring elsewhere ; it should 

 surely have been included. 



22. H tcrrcstris. I have seen var. hypozona, Moq. 

 among the English specimens, though not quite 

 characteristic. The specimens were sent to me by 

 the Rev. J. W. Horsley. 



23. Buliminus obscnrtis, var. brevis, Brown, is, I 



believe, a distinct variety. It was originally, from 

 Fifeshire, and is shorter and more inflated than the 

 type, with a more acute apex. 



24. Clausilia biplicata, var. tridentata, \ which is 

 omitted, is, I think, strictly a monstrosity. I had 

 only one specimen. 



25. C. Rolphii, var. nitida. As this name has 

 been published ("Journ. of Conch.," 1891, p. 392), 

 although not given in the list, I may as well furnish 

 a description. It is 13 mill, long and 33 broad, 

 deep red-brown, shiny, not so tumid as the usual 

 form, striae not quite so close together. This form 

 has the same dimensions as var. digonostoma, Bgt. ; 

 it was sent to me by the Rev. J. W. Horsley, and 

 collected at Plumstead. What L regard as the type- 

 form of the species, also from Plumstead, is 12 mill. 

 l° n g> 3i broad, horn-colour, shiny. 



26. C. rugosa, var. crenulata, Crowther, ^omitted 

 from the list, is preoccupied by a continental var. 

 crenulata, Risso, 1826. If Mr. Crowther's variety 

 should be considered a valid one, it must have a new 

 name; it is distinguished by "having the mouth 

 closed by a varying crenulated inner lip, the pro- 

 jections being small teeth of different lengths and 

 thicknesses." It was found at Roundhay, near 

 Leeds, and described in the " Leeds Mercury." 



27. Stenogyra octona, as well as 6". Goodalli, occurs 

 as an introduced shell in greenhouses. It is recorded 

 from near Manchester by Mr. J. R. Hardy ; and I re- 

 collect seeing some specimens years ago, but have 

 forgotten where they were obtained. 



28. Helix carthusiana, var. major, Jenner (15 mill, 

 diam.), is omitted, and no doubt rightly, as there is 

 an earlier var. major of Westerlund (18 mill. diam.). 

 Unless the minimum dimensions of the latter are' to 

 be brought down to 15 mill., Mr. Jenner's variety 

 must be dropped, or else receive a new name. 



29. Cochlicopa lubrica, var. exigua, Mke., takes the 

 place of var. minima, Siem., of the "B. Nat. Cat." 



30. Succinea suecica of the "B. Nat. Cat." is the 

 same as parvula, Pascal ; and S. acuta is probably 

 S. putris, var. limnoidea. The arrangement of 

 Succinea in the new list is very different from that of 

 my catalogue, but if a careful examination and study 

 were made of the British species and varieties of this 

 perplexing genus, no doubt the result would differ as 

 widely from both as they do from one another. 



31. Planorbis umbilicatus. If Westerlund is correct 

 in identifying this with the Helix planorbis, Linn., 

 it ought in strict priority, to be called Planorbis 

 planorbis. Macgillivray ("Conch. Text-Book," 9th 

 ed., p. 57), identifies Helix planorbis with Planorbis 

 carinatus ; very possibly Linne did not discriminate 

 between the two species now called carinatus and 

 umbilicatus. 



32. P. corneus. Why are the major and mitior 

 varieties introduced as British in the Trans. Yorks. 

 Nat. Union, left out ? 



33. Physa hypnorum, var. angulata, which is omitted,
